Insights
Neonatal sepsis treatment in Latin America shows improved antibiotic availability through the Salud Mesoamérica Initiative (SMI). However, timely and appropriate antibiotic administration rates remain low, requiring further intervention.
Area of Science:
- Global Health
- Pediatrics
- Infectious Diseases
Background:
- Neonatal sepsis is a critical cause of under-5 mortality in Latin America.
- The Salud Mesoamérica Initiative (SMI) aims to enhance maternal, newborn, and child health in impoverished Mesoamerican communities.
Purpose of the Study:
- To evaluate the administration of timely and appropriate antibiotics for neonatal sepsis in SMI-participating facilities.
- To identify facility-level factors influencing antibiotic treatment delivery.
Main Methods:
- A health facility survey was conducted at the beginning and 18 months into the SMI project.
- Medical records of 821 neonates diagnosed with sepsis across 63 facilities were reviewed.
- Multilevel logistic regression analyzed determinants of timely and appropriate antibiotic treatment.
Main Results:
- Antibiotic availability increased from 27.5% to 64.0% during the SMI project, correlating with improved administration (aOR=5.36).
- Only 26.6% of neonates received appropriate antibiotics within 2 hours of presentation.
- A decline in documented appropriate antibiotic use was observed (74.4% to 51.1%).
Conclusions:
- The SMI project initially improved antibiotic availability for neonatal sepsis.
- Rates of timely and appropriate antibiotic administration remain suboptimal.
- Future SMI phases must address barriers to effective neonatal sepsis treatment.
Abstract:
Neonatal sepsis is a leading cause of mortality among children under-5 in Latin America. The Salud Mesoamérica Initiative (SMI), a multicountry results-based aid programme, was designed to improve maternal, newborn and child health in impoverished communities in Mesoamérica. This study examines the delivery of timely and appropriate antibiotics for neonatal sepsis among facilities participating in the SMI project. A multifaceted health facility survey was implemented at SMI inception and approximately 18 months later as a follow-up. A random sample of medical records from neonates diagnosed with sepsis was reviewed, and data regarding antibiotic administration were extracted. In this paper, we present the percentage of patients who received timely (within 2 hours) and appropriate antibiotics. Multilevel logistic regression was used to assess for potential facility-level determinants of timely and appropriate antibiotic treatment. Among 821 neonates diagnosed with sepsis in 63 facilities, 61.8% received an appropriate antibiotic regimen, most commonly ampicillin plus an aminoglycoside. Within 2 hours of presentation, 32.3% received any antibiotic and only 26.6% received an appropriate regimen within that time. Antibiotic availability improved over the course of the SMI project, increasing from 27.5% at baseline to 64.0% at follow-up, and it was highly correlated with timely and appropriate antibiotic administration (adjusted OR=5.36, 95% CI 2.85 to 10.08). However, we also found a decline in the percentage of neonates documented to have received appropriate antibiotics (74.4% vs 51.1%). Our study demonstrated early success of the SMI project through improvements in the availability of appropriate antibiotic regimens for neonatal sepsis. At the same time, overall rates of timely and appropriate antibiotic administration remain low, and the next phase of the initiative will need to address other barriers to the provision of life-saving antibiotic treatment for neonatal sepsis.

01:18Additional Routes of Drug Administration
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...
01:18Routes of Drug Administration: Enteral
Enteral administration involves drug administration via the mouth in two ways: orally or sublingually.
Unlike sublingually drugs, drugs that are taken orally pass through the gastrointestinal (GI) tract and get metabolized by the liver. Once metabolized, the drug is absorbed into the systemic circulation, reaching different body parts via the bloodstream. However, while passing through the stomach,...
01:25Routes of Drug Administration: Parenteral
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...
01:22Routes of Drug Administration: Overview
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...
